IVIEASURING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 699,955, dated May 13,1902.

Application filed September 30, 1901. Serial No. 77,070. (No model.) Y

T0 all whom, it may con/cern:

Be it known that I, FRANK HUEF, of the city of St. Louis, State ofMissouri, have invented certain new and useful Improvements in MeasuringApparatus, of which the following isa full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

This invention relates to a measuring apparatus; and it consists of thenovel construction, combination, and arrangement of parts hereinaftershown, described, and claimed.

The object of this invention is to provide an apparatus for measuringliquids and cousisting of a receptacle into which the liquids areadmitted and a piston or movable partition within the receptacle andconnected to a, suitable indicator whereby the quantity or lamount ofliquid Within the receptacle will be indicated when the vpartition orpistonis' moved.

My invention consists of a measuring apparatus comprising a suitablestorage-tank,a measuring-receptacle connected to the storage-tank, sothat liquid will run from the tank into the receptacle, a valvecontrolling kthe passage from the tank to the measuring-re' ceptacle, aventpipe extending upwardlyfrom the measuring-receptacle to a levelwithv the top of the storage-tank, a piston mounted in themeasuring-receptacle, a piston-rod extending from the piston through thehead o f the receptacle, cross-arms iixed upon the outer end of thepiston-rod, connecting-rods extending forwardly from the ends of thecross-arms,

va transversely-extending shaft ymounted rabove the forward end of thereceptacle, a

'crank-arm extending from each end of said 'shaft and connected to theforward ends of said connecting-rods, an indicator-plateexf tendingupwardly from the forward end of the receptacle in front of thestorage-tank, a crank-arm extending from the center of said shaftthrough a slot in said indicator-plate, a wheel mounted in front of saidindicatorplate, a crank-pin carried by said wheel, a 'connecting-rodconnecting the crank-arm to said crank-pin, -as required, to reciprocatethe pistonin the measuring-receptacle by the r0- tation of said wheel,an indicator or'dial upon said indicator-plate, and a finger carried by'said wheel and pointing to said dial, as required, to indicate theamount of liquid in said measuring-receptacle.

Figure 1 is a front view ofthe measuring apparatus. Fig. 2 is a sideelevation. Fig.

3 is a sectional View showing the 1neasuring'' measured. The saidreceptacle 4 is providedl with a front end 5, which is connected in anysuitable manner to the base orv support 2,

Ythereby upholding the front end of the said receptacle 4. The said end5 is provided with 4an opening or passage-way 6, into which the pipe 7leads,` thereby connecting the said opening-or passage-way with the tankl.l An opening 7 a leads from the passage-Way 6 into the receptacle 4,and the passage of the liquid through the said opening is controlled bymeans of an ordinary hand-valve 8. It will thus be seen that there is aconnection between the tank 1 and the receptacle 4'and that the liquidcan be admit-ted into the said receptacle 4 as desired by operating thevalve S to open or close the opening 7*.

yThe receptacle 4 may be of any desired size to measure liquids intovarious quantities,

-and as the liquid is admitted into the said receptacle it is necessarythat the same be allowed to pass therefrom, and for this purpose Iprovide a pipe 9, extending upwardly from the upper side of thereceptacle 4 and terminating near the upper end of the tank 1, so thatno liquid can escape through the Asaid pipe Whenever the valve 8 isopened to permitthe receptacle 4 to be entirely iilled Yby liquid fromthe said tank 1. A Within the receptacle 4 is located a movable pistonor partition 10, which normally rests near the front end of thereceptacle, as shown in Fig.

3, but is operated or moved therein by the pressure of the liquidwhenever the latter is admitted from the tank 1 through the pipe 7 andthe opening 7a. I ,v

11 indicates a rod which is connected to the rear side of the movablepiston or partition 10 and which operates through an opening in IOO therear end of the receptacle 4 and is supported or guided within thebearing 12, connected to the rear end of the said receptacle 4. Air maybe admitted to the rear end of the piston-chamber ormeasuring-receptacle by mounting the piston-rod 11 loosely in itsbearing or in any suitable way.

13 indicates a rod which is attached to the rear end of the rod 11 andwhich projects laterally beyond the sides of the receptacle 4, and tothe ends of the said rod 13 are attached the rods or arms 14, whichextend forwardly to near the front end of the receptacle 4 and arepivoted to the arms 15, the upper ends of which are connected to thehorizontal rod 16. The said rod 16 is supported in bearings 17 and isturned therein whenever the piston is operated or moved within thereceptacle 4.

18 indicates a plate which is connected to the front end 5 of thereceptacle 4 and projects upwardly in front of the tank 1, and formedaround the upper edge of the said plate is a graduated plate 19. A slotor opening 20 is formed in the plate 18 in front of the rod 16, and anarm 2l, connected to the said rod 16, projects through the said slot 20and has its forward end connected to a rod 22, the upper end of which isconnected to a crank-pin 23, carried by the wheel 23, supported in frontof the plate 18. A pointer 24 is rigid with the wheel 23 and operatesover the graduated scale 19, thereby indicating the amount of liquidwhich is contained within the receptacle 4. An outlet 25 is formed atthe front end of the said receptacle 4 and is controlled by the faucet26. A handle 27 may be formed rigid with the Wheel 23, so that it andthe other operating parts can be returned to their normal positionsafter they have been operated by the admission of the liquid into thereceptacle 4. The ends of the receptacle 4 are connected together andare held rigidly in position by means of the rods 28, which extendthrough openings formed in integral lugs or ears 29, formed on the endsof the said receptacle.

The operation of the device is as follows: Liquid is admitted into thereceptacle through the pipe 7 and the passage-way 6, the valve 8controlling the passage of the liquid through the opening 7n. Before theliquid is admitted into the receptacle 4 the piston 10, which isnormally located at the front end of the receptacle 4, is forcedrearwardly byturnin g the wheel 23. The rods or connections 14 will alsobe operated, and the rod 16 will be oscillated in the bearings in whichit is supported. The connections 21 and 22, leading from the wheel 23 tothe rod 16,will be moved, and the said rod and the piston will beoperated,and the piston willdetermine the amount of liquid which can beadmitted into the receptacle. By adjusting the indicator 24 the operatorcan readily determine the amount of liquid which can enter thereceptacle,and when the required amount has been admitted thereinto thevalve 8 can be closed to prohibit further passage of liquid. Afterclosing the valve 8 the liquid may be drawn out of the receptaclethroughthe outlet-faucet 26,and the parts can then be returned to their normalpositions by operating the wheel 23, which will,through the connectionsabove described, move the piston 10 back to its normal position in thefront end of the receptacle.

I have shown the device applied to one tank; but it is manifest thatthere may be pipes leading from various tanks and all may make use ofthe same measuring device.

The receptacle 4 may be made in any desired size to measure liquids intoany quantities, and the apparatus will be found of great convenience inmeasuring liquids at the same time they are drawn out of the tank withinwhich they are contained.
